Specification of Letters Patent.

Patented June 16, 1908.

To' all whom it may concern: I

: Be it known that I, ORIN H. PEAK, of Parsons, in the county of 'Labette, State of Kansas, have invented certain new and useful Improvements in Guns, of which the fol-1 lowing is a specification.

Mg invention relates to improvements in sma arms, specifically, double-barrel shot guns, which may be'discharged through the manipulation of a single trigger.

The object of m invention is to produce 1 positive and reliable means for effectin discharge of both barrels of a double-barre gun in any preferred order of selection, and for preventmg a double discharge, that is to say, a discharge of both barrels substantially at the same time. The means which I prefer to employ, for rendering practicable and eflective the use of a single trigger for the pur ipse specified, are in part automatic and who y, positive in their operation. What constitutes my invention will be I hereinafter s ecified in detailand succinctly ure, the working mechanism directly set forth in t e appended claims.

In the accompanying drawings, which constitute a part of t is application, Figure I is a side elevation of. portion of a Remington shot (gun, representative of any preferred type, an equipped with my invention in its preferred form of embodiment. In this figinvolved in my invention is exposed, portions of said mechanism being broken away 'to exhibit the interior construction which would be otherwise concealed, The I n is shown in full lines with the breech c osed, and in dotteddines with the breechraised as in the operation of breaking? the gun, and the operation of the stop-piece-actuating-member consequent thereu on is indicated in dotted lines. In this gure, the trigger is l set for the firin of the left-hand barrel as the first barrel to e discharged in the order of firing. Fig. II is a view substantially identical with the. illustration made in full lines in Fig. I but with the illustration afforded b dotted lines in Fig. I, in Fig. II, omitte In this figure the trigger is shown in full lines in the osition it occupies after the left-hand barrel' as been fired, and the trigger stoppiece is interposed to prevent the firing of the second barrel, the position of the parts 'ri'or. to the firing of the left-hand barrel eing'iindioated in dotted lines. Fig. III is a view similar to Fig. II, showing, in full tached, but in the relative lines, the position which the parts assume after the firing of one barrel-4n this instance the left-hand barrel-and preparatory to the firing of the remaining barrel, the position of the parts after the firing of the remaining right-hand barrel bein shown in dotted lines. Fig. IV is a top p an view of a portion of the subject matter of Fig. III, the breech lever being swung to one side, as for breaking, and exhibiting the working mechanism of my device in a horizontal section, taken as upon the line IVIV of Fig. III. Fig. V is a horizontal sectional view of a portion of the subject matter of Fig. III, sectioned to exhibit the sears and the sear-actuating trigger-bar,

the latter being shown in the position for first.

firing the left -hand barrel shown in Figs..I to III, inclusive. Fig. VI is a view of a portion of the sp hiect matter of Fig. V, showing the sear-'a'ctuatmg trlg erbar shifted from the position shown in igI V to that in which it may serve to fire the right-hand barrel ofthe gun first in order of firing. Fig. VII is a perspective view of the trigger and sear-actuating trigger-bar deositions which they occupy when assemble Fig. VIII is a perspective view of the. stop-piece-actuating-member and a portion of the breech-detent of the gun, illustrative in detail of the preferred means of operatively unitin those parts. Fig, IX is a view correspon ing in general scope to Fig. III, bu showing a modified form of my device. In this figure, the trigger-stop piece is shown in full linas in of the gun as posed to prevent the firing of the second barrel after the firing of the first, irrespective of the position which it occupies when in-terthe order of the firing of the two barrels which may be selected. The oscillations of the trigger-stop-piece are shown in dotted lines, two other positionsthan that shown in full lines of said stop-piece, derived through its oscillation, being shown. The dotted po sition of the stop-p1ece, shown to the right of the full line illustration of the stop-piece, in- -dicates the extreme rearward swing of the stop-piece. The dotted position of the stoppiece, shown to the left of its full line illus-- tration, indicates the extreme forward swing of the stop-piece, wherein the trigger maybe pulled for the firing of the second barrel. Fig. X is a view corresponding substantially to Fig. V, illustrating the modified trigger-bar, shown in IX, in that position whichit mechanism of both barrels.

occupies for firing the left-hand barrel in advance of the right.' Fig. XI is a view corre sponding to Fig. X illustrating the modified trigger-bar in the positionwhichit occupies for firing theiight-hand barrel in advance of the left. Fig. XII is a transverse, vertical section on the line XIIXII of Fig. X looking toward the breech. Fig. XIII is a trans verse,vertical section on the line XIII XIII of Fig. X looking toward the breech.

tached. Fig. XIX is a detail p an view, showing a preferred mode of assemblage of the trigger-stop-piec e and the supportingmem er.

Referring to the numerals on the drawings, wherein is illustrated by way of example a gun of the hammer-less type, 1 indicates the forward end of the wood stock which is securely united to a breech-piece 2 containing the lock mechanism, as by the usual upper plate 3 and lower or trigger-plate 4 united by a bolt 5 passing through a spacing-sleeve 6. 7 indicates the barrels of the gun fastened to a forestock 8 that is operatively united to the breech-piece as by a pivot-pin 10.

11 indicates a breech-lever of the familiar side-swing type, which, by suitable mechanism of usual or preferred type, not illustrated, is adapted to cperate a breech-detent 12 that is adapted to engage and dis ngage a breech-hook 13 secured to the bottom of the barrels 7 andhaving accommodation made for its movements in the body of the breechpiece 2.

14 indicates a trigger-guard, and 15 a trigger.

Double-barrel shot guns ordinarily are provided with two triggers, one for each barrel, but my present invention contemplates, as heretofore specified, the employment of a single trigger for the actuation of the firing The elements above specified are intended to represent any double-barrel gun of ordinary or preferred construction, the mechanism of which, constituting no part of my present invention, it

' is deemed unnecessary to illustrate in detail or to specify the same to any further extent than is set forth above in view of the accompanying drawings. Sui-lice it to say in this connection that the lock mechanism of the is assumed to be provided with sears 16 and 17 of any usual or preferred construction,

and provided, preferably,wvith' oppositely extending sear-lugs 18 and 19, clearly shown, for instance, in Fig. V, as well as in other figurcs of the drawings. First in order of consideration, reference is mad"v to Figs. I to VIII inclusive of the drawings, wherein is. illustrated my invention in preferred form of embodiment. In those figures, the trigger 15 is shown as provided with a web 21, which, extending through the usual slot 22 in the trigger-plate 4, is pivoted, as upon a I pin 23, at its forward end between a pair. of upwardly projecting lugs 24 and 25, rigidly secured to or incorporated with the triggerplate 4, at a point closely adjacent to the rear end of the breech-piece 2.

In intimate connection with the web 21 of the trigger, I provide a sear'actuating-mem-' ber, herein deslgnated as the sear-actuating trigger-bar, or brlefiy the trigger-bar, 27,

shown in detail in Fig. VII. This triggerbar is,. preferably, a single piece Whose horizontal extent preferably somewhat exceeds that of the triggerand its Web. At its forward end, itis provided (see Fig. VII), by bifurcation, with cheek-plates 28. and 29, which, straddling the pivoted end of the web 21, are. provided. near their respective opposite ends with slots 30, through which the pin 23..

passes, thereby securing it in place upon the web with liberty of determinate endwise move-. ment thereon. Suchimevement, for the performance of a functiQHiLhereinafter set forth,

is designed to be in. arted to it by a member moi ably secured, in convenient position for manipulation, uponthe outside of the gun.

' I prefer to employ for this purpose a slide 31 resembling, or identical with as preferred, the usual safety, of familiar use in guns of the hammerless type. The slide 31 is provided with a web 32 working in a slot 33 in the plate 3, and operatively engaging, as between jaws 34, a tail-piece 35 upon the trigger bar 27. provided upon opposite sides with studs 37 with which the free notched end of a bifurcated spring 38, secured at its forward end, as indicated at 40, to the inner face of the plate 3, engages'the notches of the said spring serving by engagement with the studs 37 to hold the slide 31 yieldingly in as many different determinate positions as the ofiice or offices of the slide 31 may require, three The web 32 is preferably notches being shown in the drawings. In

the form of embodiment of my invention, which is shown in the drawings, only two ofthe notches are employed, the third not being necessary for the operation of the gun, unless more than two barrels are employed. Two different positions of the slide 31 arerequired for the purpose of actuating the trigger-bar 27 The one position is that shown in Fig. V and corresponding figures of the drawings, in 7111011 the front end of the slots 30 engage with the pin 23. The other position, in

gether after which the rea ends of the said slots engage with said drawings. 7

The endwise movement of the trigger-bar 27 is designed to afford means for shifting the recesses 45 and 46 (compare Figs. V,-VI, and VII) with reference to the searlu'gs 18 and 19, respectively. In the front ofthe recess 45 and in the rear of the recess 46, seartripping-faces 47 and 48, are, respectively, provided' The relative disposition of the re spective sear-tripping-faces 47 and 48, and recesses 45 and 46 is such that when the trigger-bar 27 is driven to the forward limit of its endwise movement, as shown in Fig. VI, the recess 45 underlies and registers with the sear-lug 18, the Sear-tripping-face 48 underlying and registering with the sear-lug 19.

On the other hand, if the triggerbar be retracted to its rearward limit of endwise movement, as shown in Fig. V, the relative posi-, tions of the sear-lugs, recesses, and sear-tripping-faces of the trigger-b 9.1 are reversed, the

sear-tripping-face 47 underlying and reg-- istering with the sear-lug 18, and the recess 46 underlying and registering with the searlug 19. g

In consequence of the construction and disposition of the trigger-bar with its re cesses and seair-tripping-faces, as specified, when the trigger-bar is thrust forward, as shown in Fig. VI, the lifting of the triggerbar, as by a pull upon the. tri ger 15, will serve to actuate the sear 17 in a vance of the sear 16. Reversal of the endwise movement of the trigger bar 27, that is to say its retraction to the position shown in Fig. V, will serve to'actuate the sear 16in advance of the sear 17 The reason that the .endwise movement of the trigger-bar serves to actuate the sears in difierent relative order,'as has just been specified, depends upon the difference in elevation between the sear-trippingfaces 47 toms of the recesses 45 and 46, each sear-lug of the tri ger-bar beingfitctuated by engagement with its face 47 or 48, in the one posi tion, and with the,bottom of its recess 45-01 46,.in the other position.

The trig er web 21 and the tri 'g are preferably accommodated with space for operation within -a bridge-piece '50 that issecured to the upper or inside face-ofthe trigger-plate 4 for'the reception of a screw- 51,.Which, through the-intervention of the bridge-piece, joins the plates '3 and 4. to-' the usual manner of construction. Itwill be apparent to one skilled in the art that provision 1s made, in the construction of the trigger-bar 27 with its corr'elatively disposed recesses 45 and-46, and sear-trippingfaces 47 and 48, for the consecutive actuation of the sears 16 and 17; j but, withoutother provision, the actuation of the second sear} pin, is hewn in Fig. VI of the 'as by aspring 59 coiled about the pin andii 48, respectively and the boterebar 27 specified.

block 60 should be broad enough single trigger 15, a .triggerTstop-piece 55 adapted automatically to ,interpose itself in the path of movement of the trigger each time one barrel has been fired, and automatmeans of controlling the movement of the a ically, upon voluntary release of the trigger,

to retreat out of the way of the trigger, thereby permitting the deliberate firing of the second barrel. The movement of the trigger-bar 27, previously specified, determines which barrel, .in the order of firing, shall be the first fired by the movement of the trigger- The trigger-stop-piece 55 is preferably a pond-erable member, assembled with its correlative members 111 such manner as to oscillate freely n a vert cal plane substantially parallel to the longitudinal axes of the gun barrels.- It isfrom'the requisite ponderosity of the trigger-stop-piece 55 and its modeof assemblage that its automaticity, in respect to its proper functiomis derived, as w' be hereinafter presentlyspecifi'ech The stop-piece 55 is, preferably, loosely-depend: ent from a pin- 56 secured towa supportingmember 57, fixed to the side of the plate 3, at

the proper point above the trigger 15 y and between the screw 51 and the tail-piece 35. The member 57 may. also be conveniently employed 'as. a means of securing the spring 38 inplace'. I 'Thefreeend' of the stop-piece 55 isyieldingly urged-towards the screw '51, 56 and operatively connected with the stop-piece and-With the pin" or its supporting-member 57 for imparting to the stop-piece the move-' ment which it is required to impart. The pring 59* must be lightin order tedevelop just sufficient force for the performance of its function and such as may be readily overcome by power developed in the rebound of the as and for the purpose hereinafter,

Coeperative with thestop piece 55, I provide upon the web 21 ofthe trigger, a stop block 60, which engages the stop-piece when the trigger is pulled, except when the stoppiece has moved to the extreme-forward limit of its travel, as shown in Fig. .111, thereby interrupting the upward. movement of the trigger 15 upon its pivot-pin 2-3. The stopto insure the engagement specified, and is, for assent bllH PUI' oses, a bifurcatedblock, as shown upwardlyprojecting extension 62 of the web 21, for whose accommodation, in part, an elongated slot 63 inthe trigger-bz'rr 27 is provided.

- It being an initial function of the stoppiece 55 to interpose to prevent the firing ot the second barre after the firing of the first, I provide means for positively presenting the stopepiece 55 for engagement with the stop-block 60 when the hammers of both barrels are cocked and before either is fired. That means, as shown in Figs. I. to VIII 1nclusive, consists of a Stop-p1ece-actuatmgmember 65 that is separably but operativelymg a recess provided for itin the rear of the i breech-detent 12 and engaging with the wall of saidjrecess, is a simple and preferred means of unit-mg themember 65 to the member 12.

Suitable means should be provided for properly alining the movement of the member 65, such, for example, as a pin 68 passing through the screw 51 above the upper face of the 's nember 65.

Provision having been made, as last above specified, for the setting of the stop-piece 55, it is necessary to provide means for holding the stop-piece when set in the position to which it is set. To that end, I prefer to provide upon the web 21 and extending upwardly through the slot 63-, a rearwardly deflected stop-lug 70, substantially bell-crank in shape, whichfe'ngag'ing a cross-piece 71 spanning a recess 72 in the lower end of the stop-piece 55, serves to hold the stop-piece when set in position to engage the stopblock 60. The recess 72 is provided within the lower end of the stop-piece 55, through which it extends horizontally from end to end, in order to enable the stop-lug 70 to clear the crossiece 71 after it has served the purpose ofliolding the stop-piece in the posltion to which it is set by the movement specified of the member 65. It may be observed in that connection at this juncture that a pull upon the trigger 15 serves at the same instant to bring the stop-block 60.

' and the stop-piece 55 into engagement, and

' substantially in the one position,

effectively interrupts the movement of the to disengage the stop-lug 70 from the crosspiece 71. Consequently at the moment of the disengagement of the latter pair of members, the engagement of the former pair of members continues to hold the stopspiece 55 A leaf spring 73, securedas by a trigger.

the upper face of plate 4, engagscrew 74 to ing with a pin 75 projecting-from the trlggerbar 27,. serves .to yieldingly hold the.'trigg"r wherein it- 15 in the depressed position shown, for example, in Fig. I of the drawings.

-Reserving description of the operation of the foregoing mechanism to a subsequent portion of this specification, attention is now directed to Figs. IX to XVIII, inclusive, of the drawings, wherein my invention is shown in modified form of embodiment. The principal distinctions between the modified form of embodiment .of my inven tion andthat previously described are in re spect to the means of liberating the triggerstop piece from its set position, wherein it engages the trigger and interrupts its movement, and also in the means for selectively determining the barrel which shall come first in the order of firing. As previously specified, it is the movement of the stop-lug 70 by pull of the trigger 1.5 which liberates the trigger-stop-piece, and it is the endwise movement of the trigger-bar 27 which selectively determines the barrel to be fired first. In the modified form of embodiment of my invention now under consideration, the stop-lug 70 is dispensed with, another means being substituted for the performance of its function, and an oscillatory trigger-bar is substituted for the reciprocatory triggerbar previously described.

Referring to the numerals on the figures at present under consideration, first premising that the members of the gun mechanism proper, indicated by the numerals 1 to 14 inclusive, remain unchanged and, therefore require no other identification than that afforded by the numerals re erred to, 80 indicates a trigger depending from a lever 81 working in a slot 82 provided for it in the trigger-plate 4. The lever 81 is a bent lever having an intermediate portion 83 and a fore-end 85, in which is provided a knuckle 86 for the reception of the pin 28 that )asses through the lugs 24 and 25 previously described. The knuckle portion of the foreend '85 is bifurcated for the accommodation upon the same pin 23 of a stop-piece-detent 87. The lever 81 asses through thebridgepiece 50, previous y described as affording means of connection for the screw 51 with the triggenplate 4. The deflection of the lever 81, represented by the intermediate portion 83, is provided for the accommodation of an oscillatory trigger-bar 90 that is pivotally secured, as by a pin 91, within a recess 93 providedfor it beneath a stop-block 94, the latter corresponding in function to the stop-block previously specified. The rigger-bar 90, passing between the sides of the bridge-piece 50, as illustrated in Figs. X and XI, is limited in its oscillatory movement by those members, but provision forthe said movement posed, is made by recesses 96 and 97 located l in the forward end of the oscillatory triggerwithin the limit so im- ,L at .verse shde 101, having upon its face a lug 102- p ece 55: Like-the sto -p1ece 55, the sto,p'-.

p ece 115'is susripnded sconce bar90 and the intermediate portion '83- of the a projection 98, which, as wi appe upon comparisen of Figs. X and X1, is ada t.- .e

through the "oscillatory movement of t e trigger-bar 90, to engage one or the other of the sear-lugs 18and l9, butinever both at the\ same time. The; trigger-bar 90 is. provided '10 upon each side of. the projection 98 withseartripping-faces 99 and -100,respectively, which alternatel serve to engage the remaining sear-lu or actuation of. the second sear when t e sear-lug ofthe firstsear in order of selection is englaged. by the projection 98.

Consequently, t e projection '98 corresponds, as aunit, 1n function to the two sear-trippin faces 47 and 4 8, previously specified,-W e' the sear-trlppmg-faces 99 and 100ucor1espond to-the recesses 46 and 45. In point of fact, the bottoms of the recesses may {be as properly described as seartripping-.faces.as the more elevated sear-tripping-faces' 47 and 48, and it is the space w I -ch separates the sear-tn ping faces 47 and 48 from the bottoms o recesses 45 and 46 that difierentiates 1 them from each other, and that in like manner difierentiates the member 98 and 99 and 100, respectively, from each other.

The oscillation of the trigger-bar 90 is imparted to 1t by means similar to the means employed for actuating thetrigger-bar 27,

that is to say by a member mov'a ly secured to-the outside of the gun. The member in.

the presentvinstance may consist of a transtransversely elongated in cross-section, as shown m Fig. XVI, which works in a trans- 4 by the pin 23 in the bifurcated knuckle por--' tion of the fore-end 85 of the lever 81, is normally held as by a" spring 110 secured to one end as by a screw 111 tothe rear face of the breech,- iece 2, or otherwise conveniently f ner actuated 6 dispose in engagement with a triggerrstope piece 115 identical in function with the stopom the supporting member 57 by t epin 56 and-is in e mandistinction between the] two stop-pieces is that the recess 72 in"it, being no longer needed for the stop-block 70,-for' which the detent87 is substituted, isdis'pensed with in- '-tlge;.-stop-piece 115. The end ofthe detent 87,?hidssagainsta smoothly curved face 116' y the spring 59. The material on the front face of the stop-piece -115,-'the face 116 being terminated bya shoulder 117 which affords a stop for the detent .87, and defines a recess for the end thereof, permitting the'retreat of the stop piece 115 against,

out of [the way 0 the stop-block 94. The normal positionof the sto -piece 115 being "uecto the spring-actuate interposition of the (ar a. 87 against the face 116-of thesto piecefshown in full lines in Fig. IX, 1 provi e means forsliberating' the stop-piece from engagement With'the detent 87 when required. In its nor mhl position referred to as shown in full lines in Fi IX', the stop-piece115 permitsa limited use of the lever 81 upon pull .of thetrigger 80. This movement .of the lever 81 issufficient to actuate one .or the other of the sears, whicl1 is first in order of selection. according to the osition to WhlOh the trigger-bar 90 is set. aying actuated the first sear, further movement of the. lever stop-piece 1 1 5 into engagement with the stop- .block 94; It is necessary, therefore, that the said stop-piece give way before the stopblock 94 in order that the lever 81. may,.by pull upon the trigger 80, be lifted sufficiently to actuate the second scan Accordingly,-

provide means for lifting the detent 87 agains the shoulder 117 of the detent 115 wheneve: either sear is actuated. Suchmeans ma consist simply and conveniently ofa rojec tion- 118 depending from the 4 ower ace 0 the detent S7. and engaging with both sear so that .the movement of either sear-ma actuate it to lift the detent 87.

In respect to the operation of my device it may be briefly outlined-as follows. Th gunner having determined upon the barre which'he desires to fire first, sets the slide 3 or 1, as the form of embodiment of my in vention which'he is using requires, proceed to manipulate the gun in the ordinar'y man ner, breaking it through the usual manipuls tion of the lever 11, and pullin the trigge first for one barrel and then for t e other. 1 he desires he may continue to fire one barn to the exc usion of the otherbymerely break ing and reloading after each firing-of the sir 'gle. barrel selected. The stop-piece 115, as the case may be, is always ready fc the performance of its function,..the=sto1 piece ,55 being automatically'set by its acti sting-member through. .the operation; a breaking, as often as itoccurs. The sto piece115 is always normally held in the-s1 position for the performance of its functic as a stop-piece by the detent 87 except-wile it is lifted through the actuation'of' one of ti sears.

The operation upon which depends 'tl automatic action of the stOp-piece'55or. 11 their operation inthat respect beingidel tical, requires further description. as follow or substantially -a ainst, the bridge-piece 50' "Both barrels being loaded and the gun re ady to fire, the, gunner pulls upon the triggerand thereby'discharg esthe first barrel iii-order of firing-to which the trigger-'bar'27 or 90, with.
